Guided up-sampling for image inpainting

A computer-implemented method, the method comprising:

• obtaining an inpainting result comprising valid feature patches outside of a designated portion of the inpainting result and generated feature patches inside of the designated portion, the generated feature patches determined using image inpainting;
• performing patch similarity analysis on feature patches of the inpainting result, wherein the patch similarity analysis compares the valid feature patches with the generated feature patches;
• determining a most similar valid feature patch for each of the generated feature patches based on a measure of similarity;
• mapping the most similar valid feature patches in the inpainting result to corresponding feature patches in a higher-resolution input image, the corresponding feature patches from outside a portion of the higher-resolution input image corresponding to the designated portion of the inpainting result;
• incorporating the corresponding feature patches into the portion of the higher-resolution input image during upsampling image reconstruction;
• and
• outputting a high-resolution inpainting result based on the upsampling image reconstruction.
